Which statement about the plant cell wall is true?

• A. It is thicker than in an animal cell and provides structure
• B. It stores waste
• C. It conducts photosynthesis
• D. It contains genetic material

Answer: (A)

The plant cell wall is a rigid layer made mainly of cellulose that surrounds the cell membrane to give the cell its shape and mechanical support. This structural role is especially important for plants, which need to stand upright and resist swelling from water uptake. Since animal cells lack a cell wall, the wall in plant cells serves to provide that extra rigidity, making the statement true. The wall does not store waste (that’s handled by vacuoles and other organelles), it doesn’t carry out photosynthesis (that happens in chloroplasts), and it doesn’t contain genetic material (DNA is housed in the nucleus).
